Abstract

Eosinophilia-associated myeloid neoplasms with rearrangement of chromosome bands 5q31-33 are frequently associated with PDGFRB fusion genes, which are exquisitely sensitive to treatment with imatinib. In search for novel fusion partners of PDGFRB, we analyzed three cases with translocation t(5;20)(q33;p11), t(5;14)(q33;q32), and t(5;17;14)(q33;q11;q32) by 5′-rapid amplification of cDNA ends polymerase chain reaction (5′-RACE-PCR) and DNA-based long-distance inverse PCR (LDI-PCR) with primers derived from PDGFRB. LDI-PCR revealed a fusion between CCDC88C exon 25 and PDGFRB exon 11 in the case with t(5;17;14)(q33;q11;q32) while 5′-RACE-PCR identified fusions between CCDC88C exon 10 and PDGFRB exon 12 and between DTD1 exon 4 and PDGFRB exon 12 in the cases with t(5;14)(q33;q32) and t(5;20)(q33;p11), respectively. The PDGFRB tyrosine-kinase domain is predicted to be retained in all three fusion proteins. The partner proteins contained coiled-coil domains or other domains, which putatively lead to constitutive activation of the PDGFRB fusion protein. In vitro functional analyses confirmed transforming activity and imatinib-sensitivity of the fusion proteins. All three patients achieved rapid and durable complete hematologic remissions on imatinib.

摘要

伴有染色体 5q31-33 带重排的嗜酸粒细胞相关髓系肿瘤常与 PDGFRB 融合基因相关,对伊马替尼治疗极为敏感。为寻找 PDGFRB 的新融合伙伴,我们通过 5′-RACE-PCR 和基于 DNA 的长距离反向 PCR(LDI-PCR),使用源自 PDGFRB 的引物,分析了三例具有易位 t(5;20)(q33;p11)、t(5;14)(q33;q32)和 t(5;17;14)(q33;q11;q32)的病例。LDI-PCR 显示 t(5;17;14)(q33;q11;q32)病例中存在 CCDC88C 外显子 25 与 PDGFRB 外显子 11 的融合,而 5′-RACE-PCR 则鉴定出 t(5;14)(q33;q32)和 t(5;20)(q33;p11)病例中存在 CCDC88C 外显子 10 与 PDGFRB 外显子 12 以及 DTD1 外显子 4 与 PDGFRB 外显子 12 的融合。所有三种融合蛋白均预测保留 PDGFRB 酪氨酸激酶结构域。这些伴侣蛋白含有卷曲螺旋结构域或其他结构域,可能导致 PDGFRB 融合蛋白的组成性激活。体外功能分析证实了融合蛋白的转化活性和伊马替尼敏感性。所有三名患者在接受伊马替尼治疗后均迅速获得完全血液学缓解且持久。
